She was eighteen and had been sneaking into the stables every night for weeks, heart pounding as she watched the big black stallion stamp and snort. His name was Thunder, and his cock hung heavy and dark between his legs even when he wasn’t hard. Tonight she wasn’t just watching. She stripped off her shorts and panties right there in the straw, climbed up on the mounting block, and spread her legs wide so her bare cunt was level with his muzzle.
Thunder sniffed her first, hot breath blasting over her wet slit. Then his tongue came out, rough and thick, dragging straight up her folds and making her jerk. “Fuck,” she hissed, grabbing the rail. He licked again, longer this time, the flat of his tongue pushing her pussy lips apart and flicking over her clit. She was dripping already, thighs shaking. She reached back and grabbed his halter, pulling him closer until that huge tongue was fucking into her hole in sloppy, wet strokes.
Her first orgasm hit fast and mean, cunt clenching around nothing while she ground down on his tongue. She didn’t stop. She climbed higher on the block, turned around, and bent over, reaching back to spread her ass cheeks so he could see everything. Thunder’s cock was already dropping, the head blunt and flared, veins thick along the shaft. She reached under and wrapped both hands around it, stroking the hot, leathery skin. It jerked in her grip, pre-cum already leaking in thick strings.
She lined the head up with her cunt and pushed back. The first inch stretched her so wide she screamed. It burned, splitting her open, but she kept pushing. Inch after inch of that massive horse cock sank into her tight eighteen-year-old pussy. Her belly bulged visibly. She could feel every ridge, every pulse. Thunder snorted and thrust once, driving another few inches inside her. She came again instantly, pussy spasming and squirting around the invading shaft.
He fucked her in short, brutal strokes after that, the flared head battering her cervix while she hung onto the rail and took it. Cum and her own juices poured down her thighs. Every thrust made wet, obscene noises in the quiet stable. She reached down and rubbed her swollen clit in fast circles, coming a third time with her face pressed to the wood, drooling and babbling.
When Thunder finally blew, it was like a fire hose. Hot, thick ropes of stallion cum flooded her cunt, so much that it gushed back out around his cock and splattered on the straw. Her belly rounded slightly from the sheer volume. She stayed impaled on him until he softened and slid out with a wet pop, a river of cum following. She dropped to her knees, scooped some of the mess from her ruined pussy, and licked it off her fingers while Thunder nosed at her hair.
She was already planning the next night.
